[PATCH linux dev-5.3 2/2] ARM: dts: aspeed: ast2600evb: Use custom flash layout

[Joel Stanley]

The AST2600 u-boot and kernel images have outgrown the OpenBMC layout.
While BMC machines use 128MB SPI NOR chips, we only have 64MB on the EVB
so use a layout that has a smaller region for the ro and rw filesystems.
